The DS280MB810 has strong equalization capabilities that allow it to equalize insertion loss and extend the reach of backplane channels by 17+ dB beyond the normal capabilities of the ASICs operating over the channel. The DS280MB810 is designed to apply gain in a linear fashion. Whenever system design constraints allow, the DS280MB810 should be placed with the higher loss channel segment at the input and the lower loss channel segment at the output; however, since the DS280MB810 operates in a linear fashion, it can also be used in applications where the lower loss channel segment is at the input and the higher loss channel segment is at the output. Figure 9-3 shows a typical backplane and mid-plane configuration using the DS280MB810 to perform equalization and signal distribution for failover or redundancy. Figure 9-4 shows the corresponding simplified schematic for this application.
